Debian 10 Boot Spew
I have been testing Debian 10 as a replacement for Ubuntu MATE 16.04.
At work we use a traditional
/etc/rc.local file. I am well aware the high priests of systemd have declared that file deprecated and all users are supposed to bow and say, “Amen.”
I never have been good at conforming.
After initial Debian 10 configurations I saw boot spew from the rc.local file. I ran into this event previously. I remembered I resolved the problem, but I wrote no notes. I remembered after staring at my monitor for a few moments. Almost two years ago I had seen the output spew in our Proxmox systems. I think after a major Proxmox update. Proxmox is based on Debian.
At that time I had written a
/etc/systemd/system/rc-local.service.d/debian.conf service file to silence the output spew.
# Prevent rc.local output boot spew to stdout. [Unit] After=network-online.target [Service] StandardOutput=journal StandardError=journal
I added the file to my Debian 10 test system. No more boot spew from rc.local.
